each of three mutually perpendicular
directions. There will be no visual
damage and the capacitors will meet
the limits of the table below.
Temperature Coefficient and
Drift:
Measure the capacitors’ ca-
pacitance at 25 ºC, –55 ºC, 25 ºC, 125
ºC and at 25 ºC — all ±3 ºC — after
stabilizing at each temperature. The
capacitor will meet the limits of the
Characteristic table in Ordering In-
formation.
B
ending Test:
Mount the capaci-
tor as shown below and press the ram
500 to 3000
bar until a 2.0 mm deflection is
3000
achieved. There will be no visual
damage and the capacitors will meet
Insulation Resistance
is no less the limits of methods JIS 5102 8.11
than 100 GΩ when measured at 100
and AEC-Q200-005 without crack-
Vdc
ing or visual damage.
Min. Q
Heat Resistance:
Subject the
capacitors to 125 ±2 ºC for 2 (+1,–0)
hours. Then the insulation resistance
will be no less than 5GΩ.
Withstanding voltage
is two
times the rated voltage between 5
seconds and without damage: with
50 mA or less current.
Solderability:
After 2 ±0.5 sec-
onds in molten solder with Sn-PB
between molten and solder at 235 ±5
ºC, solder coverage will be no less
than 75% when examined at 10X
magnification for flow soldering.
Life Test:
Subject capacitors to
125 ºC ±3 ºC with 1.5 times rated
voltage applied for 2000 (+72, –0)
hours. There will be no visual dam-
age and the capacitors will meet the
limits of the table below.
Solder Heat Resistance:
Sub-
ject the capacitors to molten solder
at 250±5 ºC for 5±0.5 seconds after
10 to 30 seconds pre-heating at 80
to 120 ºC. There will be no visual
damage and the capacitors will meet
the limits of the table below.
Vibration Resistance:
Subject
the capacitors to simple harmonic
motion with an amplitude of 0.06
inches; vary the frequency uniformly
from 10 to 55 Hz and return to 10 Hz,
all in one minute. Repeat that cycle
continuously for two hours in
Moisture Resistance:
Subject
the capacitors to 40 ±2 ºC at 90 to
95% humidity for 500 (+24, –0)
hours. Return to room ambient for
24 hours. There will be no visual
damage and the capacitors will meet
the limits of the table below.
